問題描述

我需要計(jì)算兩個(gè)日期之間的工作日.例如:我們?cè)?7 月 4 日放假(在美國).所以如果我的日期是日期 1 = 07/03/2012日期 2 = 07/06/2012

i need to calculate the business days between two dates. ex : we have holiday(in USA) on july4th. so if my dates are date1 = 07/03/2012 date2 = 07/06/2012

由于 7 月 4 日是假期，因此這些日期應(yīng)該是 1 個(gè)工作日.

no of business days b/w these dates should be 1 since july4th is holiday.

我有一個(gè)下面的方法來計(jì)算工作日，它只計(jì)算周末而不是假期.還有什么方法可以計(jì)算假期....請(qǐng)幫助我.

i have a below method to calclulate the business days which will only counts week ends but not holidays. is there any way to calculate holidays also....please help me on this.

  public static int getWorkingDaysBetweenTwoDates(Date startDate, Date endDate) {  
    Calendar startCal;  
    Calendar endCal;  
    startCal = Calendar.getInstance();  
    startCal.setTime(startDate);  
    endCal = Calendar.getInstance();  
    endCal.setTime(endDate);  
    int workDays = 0;  

    //Return 0 if start and end are the same  
    if (startCal.getTimeInMillis() == endCal.getTimeInMillis()) {  
        return 0;  
    }  

    if (startCal.getTimeInMillis() > endCal.getTimeInMillis()) {  
        startCal.setTime(endDate);  
        endCal.setTime(startDate);  
    }  

    do {  
        startCal.add(Calendar.DAY_OF_MONTH, 1);  
        if (startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SATURDAY   
       && startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SUNDAY) {  
            ++workDays;  
        }  
    } while (startCal.getTimeInMillis() < endCal.getTimeInMillis());  

    return workDays;  
}

推薦答案

假設(shè)您有一個(gè)包含所有假期的列表，正如您所提到的.

Let's pretend you have a list containing all the holidays, as you mentioned.

ArrayList<Integer> holidays = ...

只需在 do-while 中為 if 條件添加一個(gè)條件:

Just add a condition to your if condition in your do-while:

do {
          startCal.add(Calendar.DAY_OF_MONTH, 1);
          if (startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SATURDAY
          && startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SUNDAY
          && !holidays.contains((Integer) startCal.get(Calendar.DAY_OF_YEAR))) {
              ++workDays;
          }
} while (startCal.getTimeInMillis() < endCal.getTimeInMillis());

為簡單起見，我假設(shè) holiday 包含格式與 Calendar.DAY_OF_YEAR 相同的日期.

For simplicity's sake, I've assumed holiday contains dates in the format identical to Calendar.DAY_OF_YEAR.
